Hello,
I am wondering if I can use the 'makefile.init' to get conditional linking.
My situation is the following, I have 3 products that are largely the same,
except for a single step in handling incomming messages. So my idea was to
have them all in the same managed make project and use a define to
distinguish between the 3 'versions'. But there is one small problem, and
this is that 2 'versions' require special linker switches to enable external
memory (I'm using an ATMega128), but the 3rd version does not have external
memory and therefor does not require those linker switches.
So my question is, can I use the makefile.init to provide aditional linker
switches for the external memory and also use that file to create the
compiler define to select the 'version' I want ?
What I have in mind would be something like specifying which version I need
on the first line of the file and then provide the correct compiler/linker
switches base on that makefile variable...
If anyone knows if this is possible, or knows another way of doing this,
please let me know.
Greetings,
Han

Hello Han,
Sorry i don't know about this makefile.init thing.
But if you understood right you have 3 different setups with the same
sources. You need to set a define and some linker switches.
So I think the easiest way is to create 3 different configurations like
"Release" and "Debug" but for "Product1", "Product2" and "Product3"
where you set this compiler switch -D .. and also the specific linker
options ..
ciao
